[0002] The mixing operation of reagent tubes is a routine operation in the medical and biological fields. Common mixing devices on the market include rotating sample mixing devices, vibrating sample mixing devices and stirring sample mixing devices. The rotating sample mixing device drives the test tube to rotate to rotate the reagent in the test tube, so that the reagent generates vortex and the sample is mixed with the reagent.

[0003] The prior art discloses a synchronous mixing device which comprises a driving device and a planetary gear mechanism. The planetary gear mechanism comprises a sun gear, a planet wheel and a gear ring. The planet wheel surrounds the sun gear and is engaged with the sun gear. The gear ring is sleeved outside the planet wheel and is engaged with the planet wheel. The planet wheel is provided with a clamping mechanism for clamping the reagent tube. The planetary gear mechanism is arranged obliquely. The driving device has an output shaft which is fixedly connected with the sun gear. In the synchronous mixing device, the reagent tube is installed on the planet wheel. Under the rotation of the sun gear, the planet wheel rotates and revolves at the same time, thereby driving the reagent tube to rotate (and revolve at the same time), and the mixing effect is realized.

[0004] However, in the prior art, the planet wheel drives the reagent tube to rotate, and the reagent loaded in the reagent tube will stay for a period of time due to inertia, and then gradually rotate, so that the reagent generates vortex. However, during the gradual rotation process, the reagent may be synchronized with the rotation speed of the reagent tube, which can only utilize the mixing effect of revolution, thereby affecting the mixing efficiency. CONTENT OF THE INVENTION

[0005] Therefore, the application provides a test tube rotating mixing device to solve the problem that the reagent may be synchronized with the rotation speed of the reagent tube, which can only utilize the mixing effect of revolution, thereby affecting the mixing efficiency.

[0009] The inner side of the supporting ring is provided with a hole structure for supporting the test tube, and the hole structure is arranged eccentrically.

[0010] Optionally, the inner side of the supporting plate is provided with a "U"-shaped groove structure, and the "U"-shaped groove structure is used for mounting the supporting ring.

[0011] Optionally, the longitudinal section of the supporting frame is arranged in an arc shape.

[0016] Compared with the prior art, the present application has at least the following beneficial effects:

[0017] 1. The hole structure arranged eccentrically in the inner side of the supporting ring can drive the test tube to rotate eccentrically, which facilitates the formation of vortex in the reagent in the test tube, thereby accelerating the mixing and improving the mixing effect.
